You'll see a line in /boot/grub/menu.lst that looks something like this:
kernel /boot/vmlinuz-2.6.27-9-generic root=UUID=4c5d576a-7d38-43b2-b1d0-9bb18fdae820 ro quiet pci=nomsi
Just add the option to the end of the line, so that it looks something like:
kernel /boot/vmlinuz-2.6.27-9-generic root=UUID=4c5d576a-7d38-43b2-b1d0-9bb18fdae820 ro quiet pci=nomsi hpet=disable
